Kendrick Lamar and Alchemist were photographed in the lab together recently.

Alchemist has worked with a huge array of underground and mainstream artists, including Eminem, Cam'ron, Lil wayne, and more recently Boldy James and Prodigy. It looks as though he's got another big collaboration in the works, as he has been photographed in the studio with none other than Kendrick Lamar.

The NQM tweeted the photo earlier today. There's no confirmation on what the two are working on, but it's quite possible that it could be something for K.Dot's upcoming follow-up to the universally acclaimed good kid, m.A.A.d city.
